When I lock Windows, the connection is interrupted.

I am using FortiClient Single Sign On on our Windows devices. When I download a large file from the internet and lock the computer, the transfer is interrupted. Is there anything that can be done about this?

When using FortiClient Single Sign-On, locking the Windows computer may interrupt active connections, including large file transfers. To address this, check your power settings to ensure that the computer does not go into sleep or hibernate mode when locked.

May depend on the FortiClient version as well. 7.4.0+ should not do that, older 7.0 should not do that either. 7.2 may do that on intention to fix a reported problem.

Local account can access Internet if FSSOMA is logged in and user locks the screen.

The 7.4.0 contains

Single sign-on mobility agent (SSOMA) drops user FSSO sessions earlier.

which may ease that perceived problem. I cannot say much for the FortiClient as I'm stranger to the product, but the 7.4.0 may do better for you.
